I mentioned earlier that the Falcon derailleur looked a lot like an Eagle II.

Once I get the hub greased I'm going to try swapping derailleurs to see if the index shifter works with it.
Cool. The FR7 may help extending the life of the bearings and hub.
As for Eagle II derailleur, it seems it may be compatible with TD-One derailleur as well. Let us know how your switch goes. Post pics, if possible. A picture alone is worth 1000 words
